Description

[Technical Field]

[0001] The present invention relates to a holder for holding a long object such as a wire harness, and more particularly to a holder used when arranging a second long object along a first long object, and a harness holding structure equipped with the holder. [Background technology]

[0002] As exemplified in Patent Document 1, for example, a technology has been proposed for routing a second elongated body (a specific electric wire) at a predetermined distance from a first elongated body (another electric wire) among the electric wires that make up a wire harness, taking into consideration differences in bending characteristics (maximum radius of curvature) between multiple electric wires and ease of management.

[0003] Patent Document 1 discloses a protector for a wire harness that includes a gutter-shaped protector body through which the wire harness is inserted, and a partition wall that divides a passage in the protector body in the width direction.

[0004] The protector of Patent Document 1 allows specific electric wires from a group of electric wires in a wire harness to be routed in one passage separated by a partition wall, and other electric wires to be routed in the other passage, thereby allowing the specific electric wires to be arranged alongside the other electric wires.

[0005] However, the diameter (thickness) and number of the first elongated body often vary depending on the location where the second elongated body is placed along the first elongated body, the specifications and standards of the destination, etc., and it may become necessary to add and place a second elongated body along the first elongated body later, even in cases where the second elongated body was not originally placed along the first elongated body.

[0006] For example, if the first elongated bodies have a large diameter or there are many of them, a problem occurs in that the first elongated bodies cannot be inserted into the protector body. On the other hand, if the protector body is formed excessively large relative to the first elongated bodies in anticipation of such a problem, there is a problem in that wasted space occurs inside the protector body when the first elongated bodies are inserted.

[0007] Therefore, in the configuration of Patent Document 1, it is necessary to prepare protectors of various shapes to accommodate the diameter (thickness) and number of the first elongated bodies at the location where the second elongated bodies are arranged.

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-90505 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made in consideration of such problems, and aims to provide a holder and harness holding structure that can flexibly arrange second elongated bodies to accommodate differences in the number and diameter of first elongated bodies. [Means for solving the problem]

[0010] The holder of the present invention includes a gripping portion for gripping a first elongated body and a holding portion for holding a second elongated body arranged along the first elongated body, and the gripping portion includes a pair of gripping pieces for sandwiching the outer periphery of the first elongated body, and an elastic portion for applying an elastic force to the gripping pieces in the sandwiching direction. and an operating section for performing an opening operation to open the gripping pieces to which an elastic force in the clamping direction is applied by the elastic section, the operating section is provided with a pair of operating pieces that perform the opening operation by operating the gripping pieces in the direction opposite to the clamping direction, the operating section is provided with a pair of gripping operating members in which the gripping pieces and the operating pieces are integrally formed, and a fulcrum section that rotatably abuts the pair of gripping operating members against each other is provided between the gripping section and the operating section, and a restricting section that restricts the operating pieces from approaching each other in a gripping state in which the gripping section grips the first elongated object is provided, and the restricting section is composed of a separating elastic section that applies an elastic force in a direction in which the pair of operating pieces are separated from each other. It is characterized by:

[0011] According to the above configuration, even if the number or diameter (thickness) of the first elongated body differs depending on the location where the holding device grasps the first elongated body, the first elongated body can be clamped between a pair of gripping pieces on which the elastic force of the elastic part acts.

[0012] In this way, by easily and firmly grasping the first elongated body with the gripping portion, the second elongated body held by the holding portion can be positioned along the first elongated body.

[0013] Therefore, when the second elongated body is placed along the first elongated body, the second elongated body can be placed in a manner that flexibly accommodates differences in the number and diameter of the first elongated bodies without having to prepare various types of holders that are compatible with the number and diameter of the first elongated bodies at the placement location of the second elongated body.

[0014] Also, before An operating portion is provided for operating (i.e., opening operation) the gripping pieces to which the elastic force in the clamping direction is applied by the elastic portion. There are.

[0015] According to the above configuration, the operating portion can easily operate the gripping pieces in the direction of opening them against the elastic force of the elastic portion, so that the first elongated body can be easily gripped by the pair of gripping pieces.

[0016] Furthermore, before The operation unit is provided with a pair of operation pieces that perform the opening operation by operating the grip pieces in a direction opposite to the clamping direction, and is provided with a pair of grip operation members in which the grip pieces and the operation pieces are integrally formed, and a fulcrum part that abuts the pair of grip operation members so that they can rotate relative to each other is provided between the grip unit and the operation unit. are.

[0017] According to this configuration, the first elongated object can be firmly gripped by the gripping portion due to the elastic force of the elastic portion in the gripping direction.

[0018] On the other hand, when the gripping pieces of the pair of gripping operation parts are opened against the elastic force of the elastic part by the operation part, the opening operation can be made even easier by utilizing the principle of leverage, with the gripping parts as the point of application, the operation part as the point of force, and the fulcrum part as the fulcrum. In other words, the gripping pieces can be opened widely with a small gripping force. Therefore, the first elongated body can be easily gripped by the pair of gripping pieces.

[0019] Also ,before A restricting portion is provided to restrict the operation pieces from approaching each other in a gripping state in which the gripping portion grips the first elongated body. are

[0020] According to the above configuration, in the gripping state in which the first elongated body is gripped by the gripping portion, the regulating portion can regulate the proximity of the operating portions to each other so that the gripping pieces do not unintentionally displace in the direction of opening toward each other against the elastic force of the elastic portion, for example, when an external force acts on the pair of gripping operating portions.

[0021] Therefore, by using the regulating section to regulate the proximity of the operating sections to each other, the holding state of the first elongated body by the holding section can be maintained without, for example, the holder accidentally falling off the first elongated body or the attachment position of the holder to the first elongated body accidentally changing.

[0022] Ma Before The restricting portion is composed of a separating elastic portion that applies an elastic force in a direction in which the pair of operation pieces are separated from each other. are.

[0023] According to the above configuration, in a gripping state in which the gripping portion grips the first elongated body, the spacing elastic portion can apply an elastic force to the pair of operation portions in a direction separating them from each other. Therefore, the elastic force of the spacing elastic portion can be utilized to restrict the operation portions from approaching each other, and the spacing elastic portion itself can be securely attached between the pair of operation portions without falling off.

[0024] Furthermore, the spacing elastic portion can be elastically deformed to follow the spacing between the pair of operating portions, which varies depending on the diameter of the first elongated body, and can be interposed between the pair of operating portions to accommodate first elongated bodies of various diameters.

[0025] Furthermore, according to the above configuration, the separating elastic portion can exert an elastic force in a direction that separates the pair of operation portions from each other, and therefore, the elastic force can also act as an elastic force in a direction that sandwiches the first elongated object between the pair of gripping pieces in a gripping state in which the gripping portion grips the first elongated object.

[0026] Therefore, in the gripping state in which the gripping portion grips the first elongated body, the elastic portion and the spaced apart elastic portion work together through their respective elastic forces to firmly grip the first elongated body with the pair of gripping pieces.

[0027] In another aspect of the present invention, the separating elastic portion may be pivotally provided on one of the pair of operation pieces and may be stretched across the other operation piece.

[0028] According to the above configuration, the spacing elastic portion is pivotable relative to one of the pair of operating portions, so that when the first elongated body is grasped by the gripping portion or the second elongated body is held by the holding portion, the spacing elastic portion can be pivoted to a position that does not restrict the operating portions from coming closer together, so that the spacing elastic portion does not get in the way.

[0029] On the other hand, by pivoting the separating elastic portion from a position where the operating portions are not restricted to approach each other to a position where the operating portions are restricted to approach each other, the separating elastic portion can easily restrict the operating portions from approaching each other.

[0030] Furthermore, since the separating elastic portion is pivotally provided relative to one of the pair of operating portions, it will not separate from the operating portion, eliminating the risk of loss and facilitating parts management.

[0031] As another aspect of the present invention, the restricting portion may be configured as a proximity restricting body that is disposed between the pair of operating pieces and restricts the operating portions from approaching each other.

[0032] According to the above configuration, in the gripping state in which the gripping portion grips the first elongated body, the regulating portion can physically restrict the proximity of the operating portions to each other so that the gripping pieces do not unintentionally displace in the direction of opening toward each other against the elastic force of the elastic portion.

[0033] As a further aspect of the present invention, the operation portion may be provided with a position restricting portion that restricts the position of the proximity restricting body depending on the proximity state of the pair of operation pieces.

[0034] According to the above configuration, even if the distance between the pair of operating pieces varies depending on the diameter of the first elongated body gripped by the gripping portion, the position of the proximity restriction body can be restricted by the position restriction portion.

[0035] This makes it possible to prevent the proximity restricting body attached between the pair of operation pieces from unintentionally falling off or becoming displaced from between the pair of operation pieces by the position restricting portion.

[0036] In another aspect of the present invention, the restricting portion may be provided with the holding portion.

[0037] According to the above configuration, the holding part can be provided on a restricting part that is separate from the gripping part that grips the first elongated object, so that the operator can grip the first elongated object with the gripping part and hold the second elongated object with the holding part in different locations.

[0038] Therefore, two operations (the operation of gripping the first elongated object and the operation of holding the second elongated object) can be easily performed.

[0039] Furthermore, by attaching a regulating section in which a second elongated body is held by a holding section between a pair of operating pieces provided on the side of the holding section that grasps the first elongated body, the task of positioning the second elongated body along the first elongated body and the task of regulating the proximity of the operating pieces to each other can be performed simultaneously.

[0040] Furthermore, according to the above configuration, there is no need to provide a holding portion in the gripping portion or the operating portion, so when gripping the first elongated body with the gripping portion while operating the operating portion, the first elongated body can be easily gripped without the holding portion getting in the way. In another aspect of the present invention, the holding portion may be provided on the operating portion.

[0041] For example, since a larger distance can be secured between the first elongated body and the second elongated body than when the holding portion is provided in the gripping portion, the second elongated body can be positioned relative to the first elongated body while maintaining a mutual distance.

[0042] Furthermore, by providing the holding part on the operating part where the operator performs the opening operation, the holding part can be provided in a position that is easy for the operator to access the holder. Therefore, even when the operator attaches the second elongated body to the first elongated body later, the operator can easily attach the second elongated body to the holding part.

[0043] In another aspect of the present invention, the holding portion may be provided on the gripping portion.

[0044] According to the above configuration, the gripping portion that grips the first elongated body can be configured to have a holding portion, so that the first elongated body gripped by the pair of gripping pieces and the second elongated body held by the holding portion can be arranged close to each other in a compact manner.

[0045] In addition, the harness holding structure of the present invention is characterized in that it comprises the above-mentioned holding device and a first elongated body and a second elongated body each consisting of a wire harness, and the outer periphery of the first elongated body is held by the holding portion, and the second elongated body arranged along the first elongated body is held by the holding portion.

[0046] According to the above configuration, when a second elongated body is placed along the first elongated body, the second elongated body can be placed in a manner that flexibly accommodates differences in the number and diameter of the first elongated bodies without having to prepare various types of holders that are compatible with the number and diameter of the first elongated bodies at the placement location of the second elongated body. [Effects of the Invention]

[0047] According to the above configuration, it is possible to provide a holder that can flexibly arrange the second elongated body in response to differences in the number and diameter of the first elongated body, and a harness holding structure equipped with the holder.

DETAILED DESCRIPTION OF THE INVENTION

[0049] An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the harness holding structure 1 of this embodiment is composed of a wire harness 100 and a holder 10 that holds electric wires 101 that constitute the wire harness 100. The wire harness 100 is mounted on a vehicle such as an automobile, and is routed along a predetermined routing path in the vehicle body to connect, for example, a battery (power source) (not shown) and various electrical components (not shown), and is equipped with a plurality of electric wires 101.

[0050] The electric wire 101 is formed by covering a conductive member made of aluminum, copper, or an alloy thereof with an insulating member such as resin.

[0051] Here, the connection mode of the wire harness 100 may be changed depending on the specifications of the connection destination and the specifications and destination of the vehicle body. Therefore, the wire harness 100 is configured to have a main harness 110 consisting of a group of electric wires 101 and a sub-harness 120 consisting of a group of electric wires 101 so as to have a smaller diameter than the main harness 110. Furthermore, the wire harness 100 is configured such that the sub-harnesses 120 are attached to the main harness 110 in a state of following the main harness 110, which is attached to the vehicle body at predetermined locations along its routing path. This allows the wire harness 100 to arrange the corresponding sub-harnesses 120 along the main harness 110, and the connection mode can be changed depending on the connection destination and the specifications and destination of the vehicle body.

[0052] As shown in Figure 1, the holder 10 of this embodiment is provided at an intermediate location in the wiring path of the wire harness 100, and as shown in Figures 1 and 2(a)(b), it is provided with a holding portion 2 that holds the main harness 110, an operating portion 3 that operates the holding portion 2, and a holding portion 4 that holds the sub-harness 120 along the main harness 110. In the drawing, arrow X indicates the width direction (left-right direction) of the holder 10, and similarly, arrow Y indicates the thickness direction, and arrow Z indicates the up-down direction. As shown in Fig. 1, the thickness direction (arrow Y) indicates the direction that coincides with the wiring direction of the wire harness 100 at the location where the holder 10 is attached.

[0053] The holders 10 provided in the harness holding structure 1 of this embodiment are provided at predetermined intervals along the wiring direction of the wire harness 100, and are formed to be identical to one another. However, the multiple holders 10 may be configured to have different shapes or sizes depending on, for example, the attachment location of the wire harness 100, the diameter of the main harness 110 or the sub-harness 120, or the application, or only one holder may be provided in the wire harness 100.

[0054] The gripping portion 2 is provided with a pair of gripping pieces 21 that sandwich the outer periphery of the main harness 110, and an arc-shaped wire spring 22 as an elastic portion. The operating portion 3 is also provided with a pair of operating pieces 31 that operate the gripping pieces 21 in the direction opposite to the sandwiching direction (i.e., in the direction in which they approach each other) against the elastic force of the arc-shaped wire spring 22 in the sandwiching direction.

[0055] In other words, the grip piece 21 and the operation piece 31 are integrally formed on each of the left and right sides as part of the grip operation member 5 made of synthetic resin. The pair of grip operation members 5 is not limited to being made of synthetic resin, but may be made of other materials such as wood or steel.

[0056] Specifically, the gripping operation member 5 is a long member that has a gripping piece 21 at the top and an operation piece 31 at the bottom, each extending in the vertical direction, and that extends so that the upper end of the gripping piece 21 and the lower end of the operation piece 31 are connected together, and a pair is provided so that they are approximately symmetrical to each other.

[0057] In addition, the holder 10 of this embodiment is provided with a fulcrum portion 6 at approximately the middle in the vertical direction, i.e., the portion between the grip portion 2 and the operation portion 3, which allows the pair of grip operation members 5 to abut against each other so that they can rotate.

[0058] Specifically, as shown in Figures 2(a) and (b), at approximately the middle portion in the vertical direction of each of the pair of gripping operation members 5, there is formed a protruding rotation portion 61 that protrudes like a flange toward the opposing other gripping operation member 5, and a rotation receiving portion 62 that retreats to the opposite side of the protruding direction of the protruding rotation portion 61 so as to be able to abut against the protruding rotation portion 61.

[0059] The protruding rotation portions 61 and the rotation receiving portions 62 are disposed in a staggered positional relationship in the thickness direction of the holder 10. As a result, the protruding rotation portions 61 and the rotation receiving portions 62 abut against each other so as to be able to rotate relative to each other, changing from the state shown in Fig. 2(b) to the state shown in Fig. 2(a) when the pair of grip operation members 5 are opposed to each other in the width direction.

[0060] As a result, in the holder 10 of this embodiment, the protruding rotation portion 61 and the rotation receiving portion 62 form a fulcrum portion 6 (pivot portion) that abuts the vertical middle portions of each of the pair of gripping operation members 5 so that they can rotate against each other.

[0061] The protruding rotation portions 61 of the pair of grip operation members 5 are adjacent to each other in the thickness direction of the fulcrum portion 6. Therefore, when the protruding rotation portions 61 and the rotation receiving portions 62 are in contact with each other, the adjacent protruding rotation portions 61 engage (abut) with each other in the thickness direction. This prevents the pair of grip operation members 5 from shifting relative to each other in the thickness direction.

[0062] The gripping piece 21 extends downward from approximately the middle of the gripping operating member 5 in the vertical direction to the lower end of the holder 10, and when a pair of gripping pieces 21 are placed opposite each other in the width direction, the middle part of each gripping piece 21 in the vertical direction is formed in an arc shape so that it protrudes outward in the width direction.

[0063] The elastic portion is an elastic member (biasing member) that applies an elastic force to each of the pair of gripping pieces 21 in the direction in which the main harness 110 is sandwiched (in the direction in which the pair of gripping pieces 21 approach each other), and in this embodiment, as described above, the arc-shaped wire spring 22 that extends in an arc shape when viewed from the front is used. The arc-shaped wire spring 22 is formed of a wire material such as stainless steel or spring steel, for example.

[0064] As shown in Figures 2(a) and 3(a)(b), the arc-shaped wire spring 22 is positioned above the fulcrum portion 6 so as to surround the fulcrum portion 6 when viewed from the front, and in this state, one end is engaged with the upper part (base) of one of the pair of gripping pieces 21, and the other end is engaged with the upper part (base) of the other gripping piece 21.

[0065] As a result, the arc-shaped wire spring 22 is attached to the pair of gripping pieces 21 so as to be able to exert an elastic force on each of the pair of gripping pieces 21 in the direction in which the main harness 110 is clamped, as described above.

[0066] 2(a) and 2(b), an engagement hole 23 into which a corresponding end of each of the arc-shaped wire springs 22 is inserted and engages is formed on the outer surface of the upper part of each of the pair of gripping pieces 21. As described above, the arc-shaped wire springs 22 are disposed in a position above the fulcrum portion 6, but are also disposed so as to straddle the pair of operating pieces 31. For this reason, the pair of operating pieces 31 are formed with through holes 32 at the portions through which the arc-shaped wire springs 22 pass and in the vicinity thereof so as not to interfere with the arc-shaped wire springs 22 disposed so as to straddle the pair of operating pieces 31.

[0067] The operating piece 31 extends linearly upward from approximately the middle of the gripping operating member 5 in the vertical direction to the upper end of the holder 10, and when a pair of operating pieces 31 are placed opposite each other in the width direction, they extend at an angle when viewed from the front so that the upward movement of the operating pieces 31 causes them to move farther apart in the width direction.

[0068] As a result, the holder 10 of this embodiment is configured so that by pinching and operating the pair of operating pieces 31 with a human hand (for example, the index finger and thumb), the pair of gripping pieces 21 can be opened with the fulcrum portion 6 as a fulcrum against the elastic force of the arc-shaped wire spring 22 in the clamping direction.

[0069] The holding portion 4 of this embodiment is provided with a pair of clip pieces 41 at the tip side of one of the pair of grip pieces 21, and is arranged opposite to each other so as to be able to hold the sub-harness 120.

[0070] The pair of clip pieces 41 protrude from the outer surface in the width direction (arrow X) of the tip side portion of one of the grip pieces 21, and the opposing surfaces facing each other are formed in an arc shape corresponding to the outer circumferential shape of the sub-harness 120 so as to easily clamp the outer circumferential surface of the sub-harness 120. As a result, a sub-harness holding space capable of holding the sub-harness 120 is formed between the pair of clip pieces 41.

[0071] Furthermore, a gap 41a is formed between the tip ends of the pair of clip pieces 41, connecting the sub-harness holding space with the outside space.

[0072] The tip portions of the pair of clip pieces 41 are formed to be flexible and deformable so that the gap 41a expands in diameter so that the sub-harness 120 can be inserted through the gap 41a into the sub-harness holding space. As a result, when the sub-harness 120 is inserted into the sub-harness holding space, the pair of clip pieces 41 can hold the sub-harness 120 by utilizing their own elastic force (restoring force).

[0073] In the holder 10 of the above-described embodiment, the elastic force of the arc-shaped wire spring 22 acts in the clamping direction of the pair of gripping pieces 21, so when the main harness 110 is not gripped by the pair of gripping pieces 21, the lower ends of the pair of gripping operating members 5 (pair of gripping pieces 21) are maintained in abutment with each other, as shown in Figure 2(a).

[0074] From this state, by opening the pair of operating pieces 31 of the holder 10, a gap 21a (see Figure 3(c)) is formed between the lower ends of the pair of gripping pieces 21, and the main harness 110 can be inserted into the space between the pair of gripping pieces 21 through the gap 21a, allowing the main harness 110 to be positioned in the space.

[0075] Furthermore, by performing the opening operation using the pair of operating pieces 31, i.e., by releasing the grip, the pair of gripping pieces 21 close due to the elastic force of the arc-shaped wire spring 22, and the main harness 110 can be grasped by the pair of gripping pieces 21 with the elastic force of the arc-shaped wire spring 22 acting in the clamping direction. Thereafter, the sub-harness 120 can be arranged along the main harness 110 by holding the sub-harness 120 with the pair of clip pieces 41 that constitute the holding portion 4 .

[0076] Furthermore, even when the holder 10 of this embodiment grips a main harness 110m (hereinafter also referred to as the "second main harness 110m") (see FIG. 3(b)) having a predetermined outer diameter that is larger than the outer diameter of a main harness 110 (hereinafter also referred to as the "first main harness 110") (see FIG. 3(a)) having a predetermined outer diameter, the pair of operating pieces 31 can be opened to an opening degree corresponding to the diameter of the second main harness 110m, and the holder 10 can grip the second main harness 110m with an elastic force applied.

[0077] As shown in Figures 1, 2(a)(b), and 3(a)(b), the holder 10 of the above-mentioned embodiment is equipped with a holding portion 2 that holds the main harness 110 (first elongated body) and a holding portion 4 that holds the sub-harness 120 (second elongated body) that is arranged along the main harness 110, and the holding portion 2 is characterized in that it is provided with a pair of holding pieces 21 that clamp the outer periphery of the main harness 110 and an arc-shaped wire spring 22 as an elastic portion that applies an elastic force in the clamping direction to the holding pieces 21.

[0078] According to the above configuration, the pair of gripping pieces 21 open against the elastic force of the arc-shaped wire spring 22 to an opening degree according to the diameter and number of main harnesses 110, thereby being able to firmly grip main harnesses 110 of various diameters and numbers.

[0079] Therefore, even if the number or diameter (thickness) of the main harness 110 varies depending on the location where the main harness 110 is gripped by the holder 10, the main harness 110 can be clamped by a pair of gripping pieces 21 on which the elastic force of the arc-shaped wire spring 22 acts.

[0080] Furthermore, since the main harness 110 can be easily and firmly gripped by the gripping portion 2, the sub-harness 120 held by the holding portion 4 can be arranged along the main harness 110.

[0081] Therefore, when placing the sub-harness 120 along the main harness 110, the sub-harness 120 can be placed in a flexible manner to accommodate differences in the number and diameter of the main harnesses 110 without having to prepare various types of holders 10 that can grip the number and diameter of the main harnesses 110 at the placement location of the sub-harness 120.

[0082] For example, when installing optional electrical equipment in a vehicle in accordance with the vehicle specifications, it is generally necessary to later attach the sub-harness 120 to the main harness 110 fixed to the vehicle body. Even in such a case, the holder 10 of the present embodiment described above can easily and securely attach the sub-harness 120 to the main harness 110. Furthermore, the holder 10 of the present embodiment described above does not need to be attached to the main harness 110 in advance so that the sub-harness 120 can be wired later in anticipation of installing optional electrical equipment in the vehicle, so no extra holder is required and the holder can be made compact.

[0083] Furthermore, as described above, the holder 10 of this embodiment can hold the main harness 110 by the pair of gripping pieces 21 on which the elastic force of the arc-shaped wire spring 22 acts, and therefore does not require the time and effort of wrapping adhesive tape around the outer periphery of the sub-harness 120 together with the main harness 110, as is the case when adhesive tape is used when retrofitting the sub-harness 120 along the main harness 110, or tightening a band around the main harness 110 and cutting off the excess length, as is the case with cable ties. Therefore, the holder 10 of this embodiment can be smoothly attached even when the sub-harness 120 is retrofitted to the main harness 110, and can be flexibly adapted regardless of the diameter of the holder 10.

[0084] As an embodiment of this invention, as shown in the figure, an operating section 3 is provided which performs an opening operation to open the gripping pieces 21 to which an elastic force in the clamping direction is applied by an arc-shaped wire spring 22.

[0085] According to the above configuration, the operating unit 3 can easily operate the gripping pieces 21 in the direction of opening them against the elastic force of the arc-shaped wire spring 22, so that the main harness 110 can be easily gripped by the pair of gripping pieces 21.

[0086] In one aspect of this invention, as shown in the same figure, the gripping portion 2 is provided with a pair of operating pieces 31 in which the opening operation is performed by operating the gripping pieces 21 in the direction opposite to the clamping direction, and is provided with a pair of gripping operation members 5 in which the gripping pieces 21 and the operation pieces 31 are integrally formed, and a fulcrum portion 6 is provided between the gripping portion 2 and the operation portion 3 to abut the pair of gripping operation members 5 against each other so that they can rotate.

[0087] According to the above configuration, the elastic force of the arc-shaped wire spring 22 can be utilized to firmly grip the outer periphery of the main harness 110 with the gripping portion 2, while when the gripping pieces 21 of a pair of gripping operation members 5 are operated to open with each other using the operating portion 3, the principle of leverage can be utilized, with the gripping portion 2 as the point of action, the operating portion 3 as the point of force, and the fulcrum portion 6 as the fulcrum, so that the gripping pieces 21 can be easily opened with a small operating force.

[0088] Therefore, the pair of gripping pieces 21 can easily grip the main harness 110 .

[0089] In one aspect of the present invention, as shown in the same figure, a holding portion 4 is provided on the gripping portion 2, so that the main harness 110 held by a pair of gripping pieces 21 and the sub-harness 120 held by the holding portion 4 can be arranged close to each other in a compact manner.

[0090] Furthermore, the holding portion of the present invention is not limited to a configuration in which it is provided at the tip end portion of one of the gripping pieces 21, as in the case of the holding portion 4 of this embodiment, and can be provided in any desired location, in any desired number, size, and holding form, as long as it does not interfere with the opening and closing operation of the gripping portion 2 by the operating portion 3, the gripping of the main harness 110 by the gripping portion 2, or the holding of the sub-harness 120 by the holding portion 4. When the holding portion of the present invention is provided in the operating unit 3, for example, it may be provided on the base side of the arc-shaped wire spring 22 in the operating piece 31, as in the holding portion 4' shown by the dotted line in Figure 3(a), or it may be provided on the tip side, as in the holding portion 4'' shown by the virtual line in Figure 3(a).

[0091] In this way, by providing the holding portion 4 on the operating portion 3, when the main harness 110 is held by the gripping portion 2 and the sub-harness 120 is held by the holding portion 4, it becomes easier to arrange the main harness 110 and the sub-harness 120 with a larger gap between them than when they are provided on the gripping portion 2.

[0092] Therefore, even if there is a large difference between the bending characteristics (maximum curvature radius) of the main harness 110 and the sub-harness 120, it becomes easy to arrange the main harness 110 and the sub-harness 120 according to their respective bending characteristics.

[0093] Furthermore, in the holder 10 of this embodiment, the pair of operating pieces 31 are configured in a so-called clothespin type, which allows the pair of gripping pieces 21 to be opened by operating them in a direction toward each other, but this configuration is not limited to this, and although not shown, the holder 10 may also be configured in a so-called scissors type, which allows the pair of gripping pieces 21 to be opened by operating the pair of operating pieces 31 in a direction away from each other.

[0094] Next, holders 10A, 10B, and 10C equipped with restricting portions will be described as modified versions of the holder 10 of the above-described embodiment. However, the same components as those in the above-described embodiment will be assigned the same reference numerals and descriptions thereof will be omitted.

[0095] (Variation 1) As shown in Figures 4(a), 5(a)(b), 6(a)(b)(c)(d), the holder 10A of variant 1 (see Figure 4(a)) comprises a holder main body 10A' (see Figures 5(a)(b)) and a proximity control body 7 (see Figure 6) which is positioned between a pair of operating pieces 31 and serves as a control part that controls the pair of operating pieces 31 from coming close to each other.

[0096] Furthermore, as shown in Figures 5(a) and (b), the retainer body 10A' of variant 1 does not have an arc-shaped wire spring 22 (see Figure 1) as the elastic part as in the retainer 10 of the embodiment, but has a torsion spring 22A as described above.

[0097] The torsion spring 22A is composed of a coil portion 121 formed by winding a wire in a coil shape, and a pair of arm portions 122 extending linearly from both ends of the coil portion 121.

[0098] The coil portion 121 is housed in the internal space 6s of the fulcrum portion 6 (see FIGS. 5(a) and 5(b)) so as to be coaxial with the center of rotation of the fulcrum portion 6, and as shown in FIG. 5(a), one of the pair of arm portions 122 extends from the fulcrum portion 6 into the internal space 31s of one of the pair of hollow operating pieces 31, while the other arm portion 122 extends from the fulcrum portion 6 into the internal space 31s of the other operating piece 31. The internal space 6s of the fulcrum portion 6 and the internal spaces 31s of the pair of operating pieces 31 are in communication with each other.

[0099] The pair of arm portions 122 are arranged on the base side in the extension direction of the internal space 31s of the operation piece 31 on the left and right, respectively, and have their tip portions abutting against the inner wall 31sa of the internal space 31s of the operation piece 31 on the outer side in the width direction.

[0100] As a result, the torsion spring 22A is configured to exert an elastic force in a direction in which the pair of operation pieces 31 move away from each other, that is, in a direction in which the pair of grip pieces 21 move closer to each other.

[0101] 4(c)(d), 7(c)(d)(e), and 87(b)(d), the internal structure of the pair of operation pieces 31 is omitted.

[0102] 4(a), the proximity control body 7 is formed of a hard material having a degree of rigidity (hardness) such that it is not inadvertently deformed by a force acting, for example, when gripping the pair of operation pieces 31, while being interposed between the pair of operation pieces 31. The proximity control body 7 of this embodiment is formed of a thermoplastic resin, but may be formed of other materials such as other resin materials, metal, wood, etc., as long as it has the above-mentioned rigidity (hardness).

[0103] 6(a), (b), (c), and (d), the proximity restriction body 7 is integrally formed of a proximity restriction body main body portion 71 and a thickness direction position restriction rib 72. As shown in FIGS. 4(a), (b), (c), and (d), the proximity restriction body 7 is formed to a size that allows it to be interposed between a pair of operation pieces 31, and is formed to the same thickness (length in the thickness direction (arrow Y)) as the thickness of the grip piece 21 (see FIGS. 4(b), (c), and (d)).

[0104] 6(a), (b), (c), and (d), the proximity control body 7 is integrally formed with an upper part 73 that extends linearly in the width direction and a downward protruding part 74 that protrudes downward from the upper part 73. Furthermore, the upper part 73 of the proximity control body 7 has a pair of outer protruding parts 731 that protrude outward in the width direction (on both the left and right sides) beyond the downward protruding part 74, and the entire body is formed in a T-shape when viewed from the front (see FIG. 6(a)).

[0105] As shown in Figures 6(a), (c), and (d), the thickness direction position control rib 72 in this embodiment is formed on both sides in the thickness direction at the corner portion between the outer protrusion 731 and the downward protrusion 74 on the right side when viewed from the front, so as to connect these outer protrusion 731 and downward protrusion 74, and at the corner portion between the outer protrusion 731 and the downward protrusion 74 on the left side when viewed from the front, so as to connect these outer protrusion 731 and downward protrusion 74.

[0106] 6(a) and 6(d), the proximity restrictor 7 has a through-hole 75H formed in the thickness direction at the center position when viewed from the front, through which the sub-harness 120 can be inserted. The through-hole 75H is formed to have the same diameter as or a slightly smaller diameter than the sub-harness 120. As a result, the sub-harness 120 inserted into the through-hole 75H is held by its outer peripheral surface abutting against the inner peripheral surface 75 of the through-hole 75H. In other words, the inner peripheral surface 75 of the through-hole 75H is formed as a holding portion that holds the outer peripheral surface of the sub-harness 120.

[0107] As shown in the figure, a slit 75a is formed below through hole 75H in proximity restrictor 7, extending linearly in the vertical direction from the lower edge of through hole 75H to the lower end of proximity restrictor 7. Slit 75a is a notched groove formed with a width smaller than the diameter of through hole 75H. Through hole 75H and the space below proximity restrictor 7 communicate with each other through slit 75a. In other words, the portion of proximity restrictor 7 below through hole 75H is divided into two widthwise sides by slit 75a.

[0108] The proximity control body 7 is formed so that the sides separated by the slit 75a below the through hole 75H are able to flexibly deform so that they are spaced apart in the width direction by more than the diameter of the sub-harness 120 (see symbol 7 shown by the imaginary line in Figure 7(a)).

[0109] As a result, the slit 75a of the proximity restrictor 7 expands in the width direction, allowing the sub-harness 120 to be inserted from below through the slit 75a (see FIGS. 7(a) and 7(b)). As a result, when the sub-harness 120 is inserted from the side, the inner circumferential surface 75 of the through-hole 75H, which serves as a retaining portion, can hold the sub-harness 120 (see FIG. 7(b)).

[0110] Also, as shown in Figure 4(e) and Figures 5(a)(b), a position regulating step portion 33 is formed on the inner surface 131 (hereinafter abbreviated as "inner surface 131") in the width direction of each of the pair of operating pieces 31.

[0111] 5(a), the pair of operation pieces 31 are each formed in a linear shape that slopes outward in the width direction as it goes up. Accordingly, the position restriction step 33 is formed in a stepped shape along the inner surface 131 of each of the pair of operation pieces 31.

[0112] The position restriction step 33 is formed by a plurality of (four in this example) step portions 33a, 33b, 33b, and 33d arranged along the inner surface 131 of each of the pair of operating pieces 31. The plurality of step portions 33a, 33b, 33b, and 33d are each formed to have approximately the same size.

[0113] Specifically, as shown in Figure 4(e), the four step portions 33a, 33b, 33b, and 33d are all integrally formed with a vertical surface portion 34 extending approximately upward from the inner surface 131 of the operating piece 31, and a horizontal surface portion 35 extending approximately horizontally from the upper end of the vertical surface portion 34 along the approximately width direction to the inner surface 131 of the operating piece 31.

[0114] Here, the four steps 33a, 33b, 33b, and 33d are set as the base end step 33a, the first step 33b, the second step 33c, and the third step 33d in this order from the bottom to the top of the inner surface 131 of the operating piece 31. As shown in Fig. 5(a), the first to third steps 33b, 33c, and 33d are formed so that the inclination angles of the vertical surface portions 34 become gentler in this order, more specifically, so that the angles (αb, αc, αd) that the vertical surface portions 34 form with respect to the vertical direction become larger (αb<αc<αd).

[0115] As shown in Figures 4(a)(b)(c)(d)(e) and Figure 5(a), of the four step portions 33a, 33b, 33b, and 33d, the first to third step portions 33b, 33c, and 33d each have an engaging protrusion 36 formed on the upper part of the vertical surface portion 34 that protrudes toward the center in the width direction.

[0116] The engaging protrusion 36 is formed in a tongue-like shape so as to be elastically deformable (compressible or restorable) in the width direction (protruding direction) (see FIGS. 7(d) and (e)).

[0117] Furthermore, the first to third step portions 33b, 33c, and 33d are all formed so that the vertical length of the vertical surface portion 34, excluding the engaging protrusion 36, is the same as or slightly longer than the vertical length of the upper portion 73 of the proximity restriction body 7. As a result, as shown in FIG. 4(e), when the proximity restriction body 7 is interposed between a predetermined pair of step portions 33 facing each other in the width direction (first step portion 33b in FIG. 4(e)), the outer surface of the outer protrusion 731 of the upper portion 73 abuts against the vertical surface portion 34 of the step portion 33. Furthermore, the proximity restriction body 7 is installed so as to be sandwiched in the vertical direction between the engaging protrusion 36 and the horizontal surface portion 35 of the step portion next lower (base end step portion 33a when the predetermined step portion is first step portion 33b).

[0118] Here, in holder 10A of modified example 1, similar to holder 10 of the above-described embodiment, the spacing between pair of operation pieces 31 decreases as the outer diameter of main harness 110 gripped by gripping portion 2 increases. However, as shown in FIG. 4(a), holder 10A of modified example 1 is in a gripping state gripping main harness 110 having a predetermined outer diameter (hereinafter also referred to as "first main harness 110"), base end step portion 33a and first step portion 33b are formed so that both vertical surface portions 34 extend in a direction that coincides with the vertical direction. Furthermore, the widthwise spacing between the vertical surface portions 34 of left and right first step portions 33b is formed so that it is the same as the widthwise length of upper portion 73 of proximity restriction body 7.

[0119] As a result, when the holder 10A of variant example 1 is in a gripping state in which the gripping portion 2 grips the first main harness 110, and the proximity control body 7 is interposed between a pair of operating pieces 31, the upper portion 73 of the proximity control body 7 is stretched in the width direction against each first step portion 33b.

[0120] Specifically, as shown in Figures 4(a)(b)(c), in the gripping state in which the gripping portion 2 grips the first main harness 110, the outer surfaces of the outer protrusions 731 of the proximity control body 7 on both the left and right sides abut in a surface-contact state against the vertical surface portions 34 of the first step portions 33b of the operating piece 31.

[0121] This prevents the pair of operating pieces 31 from coming any closer to each other (see Figure 4(a)), thereby preventing the pair of gripping pieces 21 from opening unintentionally and releasing their grip on the first main harness 110.

[0122] 8(a), when holder 10A of modification 1 is in a gripping state gripping main harness 110m (hereinafter also referred to as "second main harness 110m") having a predetermined outer diameter larger than the outer diameter of first main harness 110, second step portion 33c has vertical surface portion 34 extending in a direction coinciding with the vertical direction. Furthermore, second step portion 33c is formed so that the widthwise distance between vertical surface portions 34 of left and right second step portions 33c is the same as the widthwise length of upper portion 73 of proximity restriction body 7.

[0123] As a result, as shown in Figures 8(a) and (b), when the holder 10A of variant example 1 is in a gripping state in which the gripping portion 2 grips the second main harness 110m, when the proximity control body 7 is interposed between a pair of operating pieces 31, the upper portion 73 of the proximity control body 7 is stretched in the width direction against the second step portions 33c on each of the left and right sides.

[0124] Specifically, in the gripping state in which the gripping portion 2 grips the second main harness 110m, the widthwise outer surfaces of the outer protrusions 731 of the proximity control body 7 on both the left and right sides abut in a surface-contact state against the vertical surface portions 34 of the second step portions 33c of the operating piece 31.

[0125] This prevents the pair of operating pieces 31 from coming any closer to each other (see Figures 8(a)(b)), thereby preventing the pair of gripping pieces 21 from opening unintentionally and releasing their grip on the second main harness 110m.

[0126] 8(c), when holder 10A of modification 1 is in a holding state where it holds main harness 110l (hereinafter also referred to as "third main harness 110l") having a predetermined outer diameter larger than the outer diameter of second main harness 110m, third step portion 33d has vertical surface portion 34 extending in a direction coinciding with the vertical direction. Furthermore, third step portion 33d is formed so that the widthwise distance between vertical surface portions 34 of left and right third step portions 33d is the same as the widthwise length of upper portion 73 of proximity restriction body 7.

[0127] As a result, as shown in Figures 8(c) and (d), when the holder 10A of variant example 1 is in a gripping state in which the gripping portion 2 grips the third main harness 110l, when the proximity control body 7 is interposed between a pair of operating pieces 31, the upper portion 73 of the proximity control body 7 is stretched in the width direction against the third step portions 33d on each of the left and right sides.

[0128] Specifically, in the gripping state in which the gripping portion 2 grips the third main harness 110l, the widthwise outer surfaces of the outer protrusions 731 of the proximity control body 7 abut in a surface contact state against the vertical surface portions 34 of the third step portions 33d of the operating piece 31 on both the left and right sides.

[0129] This prevents the pair of operating pieces 31 from coming any closer to each other (see Figures 8(c)(d)), thereby preventing the pair of gripping pieces 21 from opening unintentionally and releasing their grip on the third main harness 110l.

[0130] 5(b), position restriction step 33 is smaller in the thickness direction than inner surface 131 of operating piece 31 and is provided in the center in the thickness direction. On the other hand, as shown in FIGS. 6(c) and 6(d), thickness direction position restriction ribs 72 provided on proximity restriction body 7 are formed on both outer sides of proximity restriction body 7 in the width direction.

[0131] For this reason, as described above, when the proximity restriction body 7 is interposed between the pair of operating pieces 31 so as to be pressed in the width direction against any one of the left and right position restriction steps 33 (33b, 33c, or 33d), the thickness direction position restriction rib 72 is adjacent in the thickness direction to a part of the position restriction step 33, as shown in Figures 4(a), (b), (d), and (e), for example. As a result, the thickness direction position restriction rib 72 and the position restriction step 33 engage (abut) with each other in the thickness direction, and the proximity restriction body 7, while interposed between the pair of operating pieces 31, is restricted so as not to be misaligned in the thickness direction with respect to the pair of operating pieces 31.

[0132] As an aspect of this invention, as shown in Figures 4(a)(b)(c)(d), Figures 5(a)(b), and Figures 8(a)(b)(c)(d), in the gripping state in which the grip portion 2 grips the main harness 110, a proximity regulation body 7 (regulation portion) (see Figures 6(a)(b)(c)(d)) is provided to regulate the proximity of the operating pieces 31 to each other.This makes it possible to regulate the proximity of the pair of operating pieces 31 to each other so that, for example, due to the application of an external force, the pair of operating pieces 31 do not unintentionally displace in a direction in which they approach each other (i.e., in a direction in which the pair of grip pieces 21 open) against the elastic force of the torsion spring 22A.

[0133] Therefore, for example, the holder 10A will not accidentally fall off from the main harness 110, and the attachment position of the holder 10A to the main harness 110 will not accidentally change in the wiring direction (Y direction) of the wire harness 100, and the main harness 110 can be maintained firmly gripped by the gripping portion 2 of the holder 10A.

[0134] In one embodiment of the present invention, as shown in Figures 4(a)(b), 6(a)(b)(c)(d), and 8(a)(b)(c)(d), the regulating portion is composed of a hard proximity regulating body 7 that is placed (interposed) between a pair of operating pieces 31 and regulates the pair of operating pieces 31 from approaching each other.

[0135] According to the above configuration, in the gripping state in which the grip portion 2 grips the main harness 110, the proximity restriction body 7 can physically restrict the proximity of the operating pieces 31 to each other so that the grip pieces 21 do not unintentionally displace in the direction of opening toward each other against the elastic force of the torsion spring 22A.

[0136] In one aspect of the present invention, as shown in Figures 4(a)(b)(c)(d), Figure 5(a)(b), and Figure 8(a)(b)(c)(d), the operating unit 3 is provided with a position restriction step 33 (position restriction part) that restricts the position of the proximity restriction body 7 depending on the proximity state of a pair of operating pieces 31, so that the position of the proximity restriction body 7 attached to the operating unit 3 can be restricted by the position restriction step 33.

[0137] According to the above configuration, when the gripping portion 2 is in a gripping state gripping the main harness 110, the position regulating step 33 gradually regulates the position of the proximity regulating body 7 according to the proximity state of the pair of operating pieces 31, so that the pair of gripping pieces 21 can be regulated (positioned) so that they do not open unintentionally, regardless of the proximity state of the pair of operating pieces 31. Therefore, the grip portion 2 can firmly grip the main harness 110 regardless of the diameter of the main harness 110 gripped by the grip portion 2.

[0138] In one aspect of the present invention, as shown in Figures 4(a)(b)(c)(d), Figure 6(a), Figure 7(a)(b)(c)(d), and Figure 8(a)(b)(c)(d), the proximity control body 7 is configured to have a holding portion 4, making it easy to hold the main harness 110 using the holding portion 2 and the sub-harness 120 using the holding portion 4.

[0139] Specifically, the holding portion 4 is provided on the proximity restrictor 7, which is separate from the holding portion 2 that holds the main harness 110. Therefore, the worker can perform the work of holding the main harness 110 with the holding portion 2 and the work of holding the sub-harness 120 with the holding portion, in separate locations.

[0140] Therefore, two operations (the operation of gripping the main harness 110 and the operation of holding the sub-harness 120) can be easily performed.

[0141] Furthermore, by attaching a proximity control body 7, in which the sub-harness 120 is held by the holding portion 4, between a pair of operating pieces 31 provided on the side of the holding portion 2 that holds the main harness 110, the work of arranging the sub-harness 120 along the main harness 110 and the work of controlling the proximity of the operating pieces to each other can be performed simultaneously.

[0142] Furthermore, when the proximity control body 7 is positioned between a pair of operating pieces 31, the sub-harness 120 held by the holding portion 4 of the proximity control body 7 is protected from external forces by the operating pieces 31 on both sides in the width direction. Therefore, the sub-harness 120 can be stably held by the holding portion 4.

[0143] Furthermore, with the above configuration, there is no need to provide the holding portion 4 on the grip portion 2 or the operation portion 3, and the proximity restriction body 7 can be disposed between the pair of operation pieces 31 after the main harness 110 is gripped by the grip portion 2. Therefore, when gripping the main harness 110 with the grip portion 2, the holding portion 4 does not get in the way, and the main harness 110 can be easily gripped by the grip portion 2 while operating the operation portion 3.

[0144] (Variation 2) As shown in FIGS. 9(a) and 9(b), holder 10B of modified example 2 is configured to include a restricting portion different from proximity restricting body 7 included in holder 10A of modified example 1.

[0145] Holder 10B of Modification 2 includes holder main body 10B' and elastic separating bands 11 as long restricting portions that apply elastic force to a pair of operation pieces 31 in a direction separating them from each other.

[0146] The spaced elastic band 11 is made of a synthetic resin or the like and is a band-shaped (strip-shaped) member having a band width direction that coincides with the thickness direction (arrow Y).

[0147] The spaced apart elastic band 11 has flexibility that allows it to bend and deform when viewed from the front of the holder 10B, and has a length that allows it to be hung between at least a pair of operation pieces 31. One end of the spaced apart elastic band 11 in the extending direction is pivotable relative to the upper end (tip) of one of the pair of operation pieces 31 via a shaft 12 that extends in the thickness direction (arrow Y). As a result, the spaced apart elastic band 11 extends in a tongue-like shape from the tip of one of the operation pieces 31.

[0148] On the other hand, a plurality of (three in this example) engagement claws 13 (13a, 13b, 13c) are arranged along the extension direction of the other operation piece 31 on the upper part (tip side) of the inner surface 131 of the other operation piece 31. In this example, the three engagement claws 13 are set as a first engagement claw 13a, a second engagement claw 13b, and a third engagement claw 13c in that order from the base side to the tip side of the other operation piece 31.

[0149] The separating elastic band 11 has a length that allows it to removably engage with any of the multiple engaging claws 13 provided on the other operating piece 31 side, and a protruding (acute-angled) engaging protruding piece 14 is formed at the other end in the extension direction.

[0150] 10(a), 10(b), and 10(c), in the gripping state in which the gripping portion 2 grips the main harness 110, as described above, the distance between the pair of operating pieces 31 decreases as the outer diameter of the main harness 110 increases. Therefore, the holder 10B of the second modified example is configured so that the engaged protruding piece 14 of the separating elastic band 11 engages with one of the three engaging claws 13 according to the distance between the pair of operating pieces 31.

[0151] The separating elastic band 11 is stretched between the pair of operating pieces 31 in a shape that is bent and deformed into a substantially U-shape so that the middle portion in the extending direction curves downward when viewed from the front, regardless of the state in which the engaged protrusion 14 is engaged with the engaging claw 13. As a result, the separating elastic band 11 can prevent the pair of operating pieces 31 from approaching each other by utilizing the elastic force (restoring force) acting outward in the width direction when the separating elastic band 11 is bent and deformed between the pair of operating pieces 31.

[0152] That is, the holder 10B of the second modification is configured to restrict the pair of operating pieces 31 from approaching each other in multiple stages (three stages in this example) in accordance with the outer diameter of the main harness 110 gripped by the gripping portion 2.

[0153] Specifically, as shown in Figure 10(a), when a main harness 110 (hereinafter also referred to as the "first main harness 110") having a predetermined outer diameter is gripped by the gripping portion 2, the separating elastic band 11 is hung between a pair of operating pieces 31 so that the engaging protrusion 14 is engaged with the first engaging claw 13a.

[0154] Also, as shown in Figure 10(b), in a gripping state in which the gripping portion 2 grips a main harness 110m (hereinafter also referred to as the "second main harness 110m") having a predetermined outer diameter larger than the outer diameter of the first main harness 110, the separating elastic band 11 is hung between a pair of operating pieces 31 so that the engaging protrusion 14 is engaged with the second engaging claw 13b.

[0155] Also, as shown in Figure 10(c), in a gripping state in which the gripping portion 2 grips a main harness 110l (hereinafter also referred to as the "third main harness 110l") having a predetermined outer diameter larger than the outer diameter of the second main harness 110m, the separating elastic band 11 is hung between a pair of operating pieces 31 so that the engaging protrusion 14 is engaged with the third engaging claw 13c.

[0156] In either case, as described above, the separating elastic band 11 flexes and deforms between the pair of operating pieces 31, exerting an elastic force outward in the width direction, thereby preventing the pair of operating pieces 31 from coming close to each other.

[0157] In one embodiment of the present invention, as shown in Figures 10(a), (b), and (c), the regulating portion is composed of a separating elastic band 11 that applies an elastic force in a direction that causes a pair of operating pieces 31 to move away from each other.

[0158] According to the above configuration, when the gripping portion 2 grips the main harness 110, the separating elastic band 11 can exert an elastic force in a direction that moves the pair of operating pieces 31 away from each other, so that the elastic force of the separating elastic band 11 can be utilized to restrict the operating pieces 31 from coming closer to each other.

[0159] Therefore, the spaced apart elastic band 11 can be interposed between a pair of operating pieces 31 with elastic force acting thereon, so that it can be securely hung between the pair of operating pieces 31 even if the length (hanging length) of the spaced apart elastic band 11 is slightly greater than the distance between the pair of operating pieces 31.

[0160] Furthermore, according to the above configuration, the separating elastic band 11 can exert an elastic force in a direction that separates the pair of operation pieces 31. Therefore, in a gripping state in which the grip portion 2 grips the main harness 110, the elastic force can also act as an elastic force in a direction that sandwiches the main harness 110 between the pair of gripping pieces 21.

[0161] Therefore, in the gripping state in which the gripping portion 2 grips the main harness 110, the torsion spring 22A and the spaced elastic band 11 cooperate with each other by their respective elastic forces, allowing the pair of gripping pieces 21 to firmly grip the main harness 110.

[0162] In one embodiment of the present invention, as shown in Figures 9(a)(b) and 10(a)(b)(c), the separating elastic band 11 is pivotally mounted to one of a pair of operating pieces 31 and is stretched over the other operating piece 31.

[0163] As a result, for example, when the main harness 110 is gripped by the gripping portion 2 or the sub-harness 120 is held by the holding portion 4, the separating elastic band 11 can be pivoted to a position that does not restrict the proximity of the operating pieces 31 to each other, as shown in Figures 9(a) and (b), so that the separating elastic band 11 does not get in the way, and the gripping action of the main harness 110 by the gripping portion 2 and the holding action of the sub-harness 120 by the holding portion 4 can be easily performed.

[0164] On the other hand, by simply pivoting the separating elastic band 11 from a position that does not restrict proximity (see Figures 9(a)(b)) to a position that does restrict proximity (see Figures 10(a)(b)(c)), the separating elastic band 11 can easily restrict the operating pieces 31 from coming closer to each other.

[0165] Furthermore, as described above, the separating elastic band 11 is pivotally arranged relative to one of the pair of operating pieces 31, so there is no risk of it becoming separated from the holder main body 10B' and being lost, making parts management easier.

[0166] As shown in Figure 9(a), the holder 10B of variant example 2 is configured such that the holding portion 4 is provided on the gripping portion 2, but the holder of the present invention is not limited to this, and the holding portion 4 may be configured, for example, to be provided on the operating portion 3 or on the separating elastic band 11 as the separating elastic portion.

[0167] (Variation 3) As shown in FIGS. 11(a) and 11(b), a holder 10C of the third modification is configured to have a restricting portion different from the proximity restricting body 7 of the first modification and the separating elastic band 11 of the second modification.

[0168] A holder 10C of the third modification includes a holder body 10C' and a pair of locking arms 17 (17a, 17b) as restricting portions. The pair of locking arms 17 are both elongated members having a length between the pair of operating pieces 31 that allows them to be locked to each of the pair of operating pieces 31, and are formed with rigidity that prevents them from bending (elastically deforming) in normal use.

[0169] One end of each of the pair of locking arms 17 in the extending direction is pivotally attached to the tip (upper end) of one of the operation pieces 31 via a shaft 16 extending parallel to the thickness direction. Specifically, as shown in Figure 11(b), of the pair of locking arms 17, one locking arm 17a is pivotally attached to one end face of the operating piece 31 in the thickness direction, and the other locking arm 17b is pivotally attached to the other end face of the operating piece 31 in the thickness direction.

[0170] Each of the pair of locking arms 17 is provided with an engagement recess 18 (18a, 18b, 18c, 18d, 18e) at the other end in the extension direction thereof, which engages with the tip end side of the other operating piece 31 (engagement pins 19a, 19b (see FIG. 11(b)) described later). As shown in FIG. 12(a), the engagement recess 18 is formed so as to recess upward from the lower edge of the locking arm 17 (17a, 17b) when the locking arm 17 is arranged substantially horizontally. A plurality of engagement recesses 18 (five in this example) are arranged along the extension direction of the locking arm 17. In this example, the engagement recesses 18 provided on each of the pair of locking arms 17 are set as a first engagement recess 18a, a second engagement recess 18b, a third engagement recess 18c, a fourth engagement recess 18d, and a fifth engagement recess 18e, in this order from the base end to the tip end.

[0171] 11(a)(b) and 12(a)(b)(c)(d), an engagement pin 19 (19a, 19b) that engages with one of the engagement recesses 18 formed in the locking arm 17 is provided at the tip of the other operating piece 31. Specifically, as shown in FIG. 11(b), the engagement pin 19 includes a one-side engagement pin 19a that protrudes in one direction in the thickness direction from one end face in the thickness direction of the tip of the other operating piece 31, and an other-side engagement pin 19b that protrudes in the other direction in the thickness direction from the other end face in the thickness direction.

[0172] Here, as described above, the distance between the pair of operation pieces 31 varies depending on the diameter of the main harness 110 gripped by the pair of grip pieces 21. For this reason, the holder 10C of variant example 3 is configured so that one of the five engagement recesses 18 provided on each of a pair of locking arms 17 engages with the engagement pin 19 of the operating piece 31, depending on the spacing between the pair of operating pieces 31.

[0173] Specifically, of the pair of locking arms 17, one of the engagement recesses 18 provided at the tip of one of the locking arms 17a engages with one of the engagement pins 19a provided at the tip of the other operating piece 31, and one of the engagement recesses 18 provided at the tip of the other locking arm 17b of the pair of locking arms 17 engages with the other engagement pin 19b provided at the tip of the other operating piece 31.

[0174] For example, as shown in Figures 12(a) and (b), in a gripping state in which a main harness 110 (hereinafter also referred to as the "first main harness 110") having a predetermined outer diameter is gripped by the gripping portion 2, a pair of locking arms 17 are hung between a pair of operating pieces 31 so that each fifth engagement recess 18e is engaged with the engagement pin 19.

[0175] Also, as shown in Figures 12(c) and (d), when the main harness 110m (hereinafter also referred to as the "second main harness 110m") having a predetermined outer diameter larger than the outer diameter of the first main harness 110 is held by the holding portion 2, the locking arm 17 is hung between a pair of operating pieces 31 so that the engagement pin 19 is engaged with the second engagement recess 18b.

[0176] In this way, the pair of locking arms 17 are hung between the pair of operating pieces 31 in a substantially horizontal position by selecting appropriate engagement recesses 18 (more specifically, engagement recesses 18 that can lock the locking arms 17 to the pair of gripping pieces 21 in a position that is as horizontal as possible) and engaging with the engagement pins 19, regardless of the diameter of the main harness 110. In other words, the pair of locking arms 17 are arranged so as to be stretched in the width direction between the pair of operating pieces 31, and therefore the pair of operating pieces 31 can be stably restricted so as not to come close to each other.

[0177] 11(a) and 12(a), (b), (c), and (d), holding portions 25 (25u, 25d) for holding the sub-harness 120 are provided in the center of the pair of locking arms 17 in the extending direction. The holding portions 25 hold the sub-harness 120 by sandwiching it from above and below, the sub-harness 120 extending along the main harness 110, with the pair of operating pieces 31 locked together by the pair of locking arms 17.

[0178] Specifically, the holding portion 25 is composed of a sub-harness support portion 25d provided in the center of the extension direction of one of the pair of locking arms 17, 17a, and a sub-harness holding portion 25u provided in the center of the extension direction of the other locking arm 17b.

[0179] The sub-harness support portion 25d is curved so that the upper edge is concave in an arc downward so that it can support the sub-harness 120 from below, which passes through the center of the extension direction of one of the locking arms 17a in the thickness direction (arrow Y).

[0180] The sub-harness holding portion 25u is curved so that the lower edge is concave in an upward arc so that it can hold down from above the sub-harness 120 that passes through the center of the extension direction of the other locking arm 17b in the thickness direction (arrow Y).

[0181] When the pair of gripping pieces 21 are fastened by the pair of fastening arms 17, respectively, a space is formed between the sub-harness supporting portion 25d and the sub-harness holding portion 25u in which the sub-harness 120 can be placed. In other words, when the pair of gripping pieces 21 are fastened by the pair of fastening arms 17, respectively, the upper edge of the sub-harness supporting portion 25d and the lower edge of the sub-harness holding portion 25u are arranged on either side in the vertical direction with a vertical distance therebetween that is equal to or slightly smaller than the diameter of the sub-harness 120.

[0182] The sub-harness holding portion 25u and the sub-harness support portion 25d hold the sub-harness 120, which is arranged to pass through the space formed between them, by sandwiching it from both the top and bottom sides between the lower edge of the sub-harness holding portion 25u and the upper edge of the sub-harness support portion 25d.

[0183] Next, the procedure for holding the main harness 110 (first main harness 110) with the holding portion 2 and holding the sub-harness 120 with the holding portion 25 will be explained using Figures 13(a)(b)(c) and Figures 14(a)(b)(c)(d)(e)(f). First, as shown in FIG. 13(a), the pair of operating pieces 31 are not locked by the locking arms 17, that is, the pair of operating pieces 31 are not restricted by the locking arms 17 so as not to come close to each other.

[0184] In this state, the pair of operating pieces 31 are operated in a direction to move closer to each other, and the pair of gripping pieces 21 are opened to an opening degree that allows the main harness 110 to be gripped against the elastic force of the torsion spring 22A.

[0185] In this state, the main harness 110 is placed in the space between the pair of gripping pieces 21 through the gap 21a (see Figure 3(c)) between the lower ends of the pair of gripping pieces 21, and by releasing the grip of the pair of operating pieces 31, the main harness 110 can be grasped by the pair of gripping pieces 21 as shown in Figures 13(b) and (c).

[0186] 14(a) and 14(b), the engagement recess 18 (the fifth engagement recess 18e in this example) provided at the tip of one locking arm 17a is engaged with the one-side engagement pin 19a provided at the tip of the other operating piece 31 in the same procedure as described above. As a result, one locking arm 17a is hung between the pair of operating pieces 31 in a substantially horizontal position, and the pair of operating pieces 31 can be temporarily restricted by one locking arm 17a so that they do not approach each other. At the same time, one locking arm 17a can be installed so that the concave upper edge of the sub-harness support portion 25d provided in the center in the extension direction faces upward.

[0187] 14(c) and 14(d), the sub-harness 120 is placed on the sub-harness support portion 25d provided on one of the locking arms 17a. As a result, the sub-harness 120 placed on the concave sub-harness support portion 25d is supported (temporarily held) from below by the sub-harness support portion 25d in a stable state in the width direction.

[0188] 14(e) and 14(f), in the same manner as described above, the engagement recess 18 (the fifth engagement recess 18e in this example) provided at the tip of the other locking arm 17b is engaged with the other-side engagement pin 19b provided at the tip of the other operating piece 31. As a result, the other locking arm 17b is also hung between the pair of operating pieces 31 in a substantially horizontal position, and the pair of operating pieces 31 can be restricted (mainly restricted) by the pair of locking arms 17 so that they do not come close to each other.

[0189] At the same time, the sub-harness 120 can be held from above by the sub-harness holding portion 25u provided in the center of the other locking arm 17b in the extension direction. As a result, as described above, the sub-harness 120 can be held by being sandwiched between the sub-harness holding portion 25u and the sub-harness support portion 25d. By the above-described procedure, the sub-harness 120 can be fixed in a state in which it is arranged along the main harness 110 using the holder 10C.

[0190] As described above, the holding portion 25 can properly (firmly) hold the sub-harness 120 through a two-step procedure in which the sub-harness support portion 25d stably supports the sub-harness 120 from below, and then the sub-harness holding portion 25u holds it down from above.

[0191] Furthermore, the action of engaging the engagement recess 18 with the engagement pin 19 when restricting the main harness 110 to be held by the gripping portion 2, and the action of clamping the sub-harness 120 from both the top and bottom sides between the sub-harness holding portion 25u and the sub-harness support portion 25d when holding the sub-harness 120 by the holding portion 25, can be performed by the same action of locking a pair of operating pieces 31 with the locking arm 17. Therefore, it is possible to easily hold the main harness 110 by the gripping portion 2 and the sub-harness 120 by the holding portion 25 using the holder 10C.

[0192] The present invention is not limited to the configurations of the above-described embodiments, but can be formed in various other embodiments. For example, the retainer of the present invention may be provided with a vehicle body attachment portion such as an anchor portion, so that it can be attached to the vehicle body.

[0193] In addition, in this embodiment, the wire harness 100 includes one sub-harness 120 for one main harness 110, but the wire harness of the present invention is not limited to this, and may be configured to include, for example, a plurality of main harnesses 110 and a plurality of sub-harnesses 120 depending on the connection destination, the specifications and destination of the vehicle body, or the wiring location. Furthermore, each of the main harness 110 and the sub-harness 120 is not limited to being configured to be made up of a group of a plurality of electric wires 101 as in this embodiment, and may be configured to include at least one electric wire 101.

[0194] Furthermore, the present invention may employ a main line instead of the main harness 110 as the first elongated body, and may employ a branch line branched off from the main line 110 as needed instead of the sub-harness 120 as the second elongated body.

[0195] Furthermore, the elastic portion provided in the present invention is not particularly limited as long as it is formed of a material that can be elastically deformed (flexibly deformed), such as metal, resin, rubber, etc. When the elastic portion is a spring, it may be, for example, either a wire spring or a leaf spring. The wire springs include, for example, torsion coil springs such as the torsion spring 22A applied to the holders 10A, 10B, and 10C of modified examples 1 to 3, wire springs such as the arc-shaped wire spring 22 applied to the holder 10 of this embodiment, as well as compression coil springs and tension coil springs.

[0196] For example, holder 10 of the above-described embodiment may use another spring, such as torsion spring 22A, as the elastic portion instead of arc-shaped wire spring 22. Similarly, holders 10C, 10B, and 10C of modifications 1 to 3 may use another spring, such as arc-shaped wire spring 22, as the elastic portion instead of torsion spring 22A.

[0197] Furthermore, the holder of the present invention is not limited to having the elastic portion as a separate member from the gripping portion 2 or the holding portion 25, but may be formed by imparting an elastic function to at least one of the gripping portion 2 and the holding portion 25, for example, by forming the gripping portion 2 or the holding portion 25 itself to have an elastic function, like a clip.

[0198] The holding portion of the present invention is not particularly limited as long as it is configured to hold the sub-harness 120, for example, by fastening with a clip, a cable tie, a long member such as a plastically deformable wire, or a fastening member such as a bolt.
